Hello,

Would I run into any problems with a breeding pair of Uaru and a breeding pair of H. Atabapo in a six foot 125g? Also, would the tank be large enough to start with a group of each species until pairs formed?

Thank you,
Aaron
 
I have seven uarus and three severums in my 125 some might say its overstocked but my water quality is good. As for the breeding severums and uarus cant breed theyre different genus. As far as im aware at least they will not breed.
 
Do either species breed? I am only worried about once spawning begins.
 
IMO it's a tight fit. My Atabapo pair have dominated a 210 gallon (72"x24"x30"). Another large pair of cichlids in the same tank could turn into war pretty quickly. Uaru are large fish and considerably more bulky than severums.

You could probably raise small groups of each species in your tank; four individuals of each would probably be okay for a while. Keeping multiple pairs is where you'll see a problem, IMO.

Make sure to really stay on top of water quality with the Uaru.
 
Ryan,

I was thinking it would be tight, sigh so hard to choose. Each species is interesting in its own right.

Do you have a thread documenting the breeding/spawning behavior of your pair? What has attracted me too the Atabapo is the delayed mouth brooding and how they will call their fry into their mouths when threatened.

When you say they dominate a 210g, do they claim more than half of the tank? What tank mates do you have with them?
 
Actually, I do have a few pictures and video here: http://www.monsterfishkeepers.com/forums/showthread.php?t=399753

The fish share the tank with a big Hoplarchus psittacus, another large male Atabapo sev, 2 Crenicichla lenticulata, and a Crenicichla saxatilis. There were also 2 male rotkeil sevs in the tank but I had to remove them because they were getting the crap beaten out of them. My Atabapo pair would attack them on the left side of the tank and my Lents would attack them on the right side, so they hung in the middle at the very top of the tank.

The pair has spawned every two weeks since I started that thread. Every time I siphon out the free-swimmers, they start fanning and defending the spawning site again and have eggs within days. They hold the fry fine in the community tank and actually defend them very well -- they usually last a week or two after free-swimming. My saxatilis pike is small and quick, and he's constantly darting in and gobbling up fy.

The fish spawn on the far left end of the tank but defend about 60 - 70% of it. My pikes, the psittacus, and the lone Atabapo sev cower at the far right side. Occasionally the pikes get brave and flare up at the pair, but the sevs are not afraid to attack any of the other fish. My psittacus was the meanest fish I owned until I got these guys, and now they have put him in his place.

I will say that this is my favorite severum that I've ever spawned, and I've spawned lots -- greens, gold, notatus. The parental care and the bond between the parents is really fun to watch.

I also have a true H. severus pair from the Orinoco. There are subtle differences in their appearance but they're definitely different than my Atabapos. They are still small, about 5", but they spawned last week. I now have two female mouthbrooder sevs holding eggs in two separate tanks.
 
Ryan,

Thanks for the detailed response. If your pair is dominating that much of a 210g than I would be silly to try to squeeze in a pair of Uaru. I had no idea they had so much attitude. I'm thinking they will love my water, PH 6, GH and KH 1-3.

How did you go about pairing them? I'm considering ordering the Atabapo Jeff Rapps has on his site now, hopefully I can make my mind up before they are gone. I am not sure if I should go with the typical six or invest in a few more to hopefully get better bonds.
 
I actually bought this pair from jgentry so they were bonded when i got them. Honestly though, there is no difference in the appearance of the male and female. I have tried hard to find a way to easily differentiate, and so far all I see different are the breeding tubes. The are the same size, have the same finnage, same red coloration, and neither has many freckles on its gills (I was told a long time ago that males would have them and females wouldn't, but both fish have a few).

Getting six is probably a good way to get a pair. I always buy everything in groups of six. That's the discus keeper in me. ;)
 
Ryan,

Ah, your lucky to have found a pair already. If I can't find them local than I might have to buy six (they are not cheap), but I feel like I have better luck when I buy 8-10.

Thanks for all of your help, I will have to post some pictures when I get my group.
 
Ryan,

I bought the f1's that jgentry, so I will be working with your fishes offspring. Hopefully I get a pair as nice as yours.
